I still see some disadvantages for laser or BlueTrack based mice:

1/ They do not work on crystal or clear surfaces

2/ I find batteries (even rechargable) a PITA :-)

3/ There are also some security concerns in using wireless for input
devices but nowadays I think the data flow between sender and receiver
units can be encrypted

For sporadic usage or to use with notebooks/netbooks/ipods/ipads/tables,
they can be nice and convenient.

For intensive usage, heck... leave me with my Cherry corded keyboard with
a weight of ~1,8 kg and its characteristic "clack, clack" sound ;-)

I've got two simple and good keyboards, one seems to be a Cherry and the
other is better, because it's good + silent. The Cherry (or Cherry like)
has got a very old connector and needs an adaptor for PS/2 usage. I
don't like the Cherry, but I'm still an old school two finger fast and
heavy writer, a relic from the 80's when I programmed in Assembler.

There's no reason that an optical mouse has to be wireless. Similarly,
there's no reason that a wireless mouse has to be optical. I've used
wired (USB) optical mice for ages now and love the fact they they never
get sticky. I find that ball mice gum up with detritus and you need to
give them a good shove to get the ball to move. Optical mice always
respond immediately.

As for not working on clear surfaces, consider yourself lucky. Sun
optical mice (e.g. http://www.memoryxsun.com/3701398.html) require a
specific mousepad with a calibrated grid printed on them. The mouse can
only report its movement relative to this grid (rather than relative to
an arbitrary surface as with modern mice).

True.

But I was replying to a KS post where he was talking about wireless mouse
with an USB receiver so the three points I mentioned were on that line.

I use alcohol to clean the ball and internal rollers. But I'm afraid
laser based mice get also dirty (bottom surface has also to be cleaned
for fast sliding). But as I said on my previous post to Ron, I can live
with them. What happens is that modern mice are a bit "ostentatious" and
full of buttons (or they're targeted to notebook users and are a bit
small).

Yes, I'm very picky with my input peripherals :-)

He, he... from what century is that piece of hardware? Nineties?

An aesthetic faux pas.
